EATON CND Series Electronic Molded Case Circuit Breakers, NG Frame

Eaton CND Series electronic moulded case circuit breakers (MCCBs) are used in low-voltage electrical systems to protect against overloads and short circuits. These circuit breakers feature electronic trip units that provide protection and monitoring capabilities.

Filter

Features

  • They have a moulded case construction, which provides durability and protection against mechanical damage.
  • These CND Series electronic moulded case circuit breakers have amperage ratings up to 1200A.
  • They feature three pole configuration for controlling multiple connections simultaneously.
  • These moulded case circuit breakers are equipped with electronic LSIG trip units to prevent a long time over current.
  • They further feature zone selective interlock communication to prevent unintended tripping of downstream breakers when upstream breaker trips.

Standards and Approvals

  • UL
  • HACR

Frequently Asked Questions

How does an electronic LSIG trip unit work in MCCBs?

  • The electronic LSIG trip unit continuously monitors the current flowing through the circuit breaker and trips the breaker if an overcurrent condition is detected.
  • The unit uses microprocessors and algorithms to accurately determine the current magnitude & duration and to provide selective coordination with other devices in the electrical system.

What are the interrupt ratings of these circuit breakers?

  • 85kAIC at 240VAC
  • 50kAIC at 480VAC
